Abstract (en)
[origin: WO2004065020A1] Disclosed is a method for interspersing a gas flow (8) with liquid droplets (5), according to which the liquid droplets (5) are injected into the gas flow (8) on a specific liquid injection plane (50). An auxiliary gas (6.1, 6.2) is injected into the gas flow (8) at the same time as the liquid droplets (5). The injection rate of the auxiliary gas (6.1, 6.2) is greater than the injection rate of the liquid droplets (5) such that the injected auxiliary gas (6.1, 6.2) stabilizes the injected liquid droplets (5) regarding the trajectory and size thereof, partly shields the injected liquid droplets (5) from the gas flow (8), and/or entrains the injected liquid droplets (5) into the gas flow (8), whereby the spatial distribution of the liquid droplets (5) and the size distribution thereof can be better controlled. The liquid droplets (5) penetrate the gas flow (8) in a more efficient manner than they would without auxiliary gas (6.1, 6.2). In a preferred application, the inventive method is used for online wet cleaning a gas turbine compressor.
